Serial No. 426,018,

provide a paper feed mechanism by means of which the wrappers are accurately fed from a roll'of paper and cut off in proper relation to the design appearing I on the wrappers.

A further object is to provide a machine having these advantages which is entirely automatic in operation.

Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention' is defined in the claims. I

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawings, in which:

Fig. 1 is a fragmentary side elevation of a wrapping machine embodying the features of my invention.- v

' Fig. 2 is a fragmentary planview with certain parts in section showing details of the contact means of the electrically controlled paper feed means.

Fig. 3 is a fragmentary side elevation partially in vertical section on line 33 of Fig.

' 4 showing further details of the electric control mechanism.

Fig. 4 is a detail .view partially in section on line 44 of Fig. 3.

Fig. 5 is an enlarged fragmentary perspective view of certain parts of the electric con-. trol mechanism.

Fig.6 is a fragmentary section with parts shown conventionally on line 66 of Fig. 1 showing further details of the mechanism and its control. I

In the accompanying drawings I have no illustrated the details of the article feed and wrapping machanism, which is designated generally by the numeral 1. It will be understood that my present improvements have particularly to do with the delivery of the paper to the wrapping mechanism in proper relation to the package or article to be wrapped so that the design appearing onthe 7 paper feed wrapper isin proper position on thepackage or in proper register therewith.

The frame 2 is common to the paper feed and wrapping mechanism and is of suitable design to support the operating parts.

The roll 3 of paper is rotatably supported by the cores 4 mounted onthe shaft 5. The

web 6 of paper has suitable repeated designs indicated conventionally at '7 thereon and has aseries of perforations 8 in definite relation to the designs, each design section constituting a wrapper.

The paper is driven by the rolls 9 and 10,- and the shaft 11 of the lower roll is provided with a pinion v12 meshing with a pinion 13 on the shaft 14 of the upper roll.

At the rear of the feed rolls-is a cutter mechanism comprising the roll 15 having a longitudinal groove 16 therein to receive the knife 17 on the rotary cutter 18.

j The shaft 19, see Fig. 1, is provided with a beveled pinion 2O meshingwith the beveled gear 21 driven by the sprocket chain 22 on the driving sprocket 23, the shaft 24: of

which is in drlving relation to the wrapping mechanism. The driving connections are not here illustrated.

The feed roll 9 is provided with a pinion A 25, see the left hand side of Fig. 1 and Fig. 4,

which is connected to a pinion 26 on the shaft 19 through a gear 27 which constitutes a tlining gear; that is,it determines the amount of paper fed for each wrapper. The spindle 28 of this timing, or transmission gear is mounted in a vertical slot 29 in the bracket 30 so that the spindle may be'adjusted in accordance with the size of the gear employed.

It is evidentthat by varying the size of this gear the relative speed of the feed roll is controlled.

The cutter 18 is connected to the shaft 19 .by a gear 31 on the shaft of the cutter 18.

shaft 11 of the feed roll so that when these clutch members are in engagement, the feed rolls are driven but stand idle when the clutch is released. I have not illustrated the details of this clutch as clutches of this type are well-known in the art, and any suitable clutch may be employed in this relation.

To prevent overthrow and overrunning of the feed rollswhen the clutch is released, I provide a band brake coacting with a drum 36 on the shaft 11, see Fig. 4. One end of the band 35 is connected to the bracket 37 by means of the bolt 38 and the other end of the band is engaged with the bolt and urged outwardly by means of the coiled spring 39 on the bolt. A thumb screw 40 is provided for adjustment of the brake.

The clutch is controlled from the cam 41 and the'electrical control which will be hereinafter described. The cam 41 coacts with the lever 42 pivoted at 43 and connected by the link 44 to the arm 45 on the shifting lever 46 which, is pivoted at 47 to coact with the clutch member 34. The link 44 is provided with a spring 48 through which the power is connected to the lower end of the lever 42 reciprocatingly mounted at 52 and 53, see Fig. 3. The latch 49 is pivoted on a collar 54 on this rod 51. The latch is supported at its opposite end by the link 55 pivoted to a fixed part of the frame at 56 and to the latch at 57 A stop latch.

The detent 60 pivoted at 61- and connected to the armature 62 of the electromagnet or solenoid 63 coacts with this latch to hold the clutch in engagement until the electromagnet is energized to release the latch.

The parts are actuated to latching position by means of the coiled spring 64 arrangedupon the rod 51 with one end'in engagement with the thrust block or collar 65 of electrical insulating material and the other with the support 52, so that the spring acts to urge the upper end of the lever against the cam disk 41 58 limits the downward swing of this The electromagnet or solenoid 63 is controlled by the contact disks 66 coacting with the contact bar 67 which is ground in the frame of the machine. The contact disks 66 are mounted in holders 68 carried by the pivoted arms 69 on the brackets 70 carried by the contact rod 67 The holders 68 are of elecnection consisting of the contact 73 connected by the wire 74 to the electromagnet. This contact 73 is insulated from the frame as indicated in Fig. 4 and is engaged by the collar or latch carrier 54 on the rod 51 when the latch is in locking position, thereby com pleting the. circuit when the contact disks 66 engage the contact rod 67 through the openings v8, actuating the electromagnet and releasing the clutch through the mechanism described, and stopping the feed of thepaper in proper relation to the designs appearing thereon so that the successive wrappers are severed at the proper point.

As the cutter rolls and, consequently, the

cam 41 are continuously driven, the cam acts to re-engage the clutch and thereby drive the feed-rolls. The result is that the wrappers are severed from the web at the proper point relative. to the series of designs appearing thereon, and the wrappers are fed to the wrapping mechanism in proper synchronism with the actuation of the wrapping mechanism. As stated, the details of this wrapping mechanism are not illustrated as they orm no part of my present invention.

To properly aline the web or roll of paper its supporting spindle 5 is mounted for lon- 'itudinal adjustment 'in its bearings 75. larallel with this spindle 5 I mount a screw 7 6 having a grooved adjusting nut 77 therein engaging the flanged collar 78 on thespindle so that, by rotating the adjusting nut, the spindle is moved longitudinally. A locking nut 7 9 is provided for holding the nut' 77 in its adjusted positions.

By this means'the web of paper can be adjusted to properly aline with the wrapping mechanism and with the contact rollers 66. The brackets 70, however, are adjustably mounted on the contact rod 67 so that they may be adjusted to the particular width of the wrapper or other spacing of the holes 8.

To tension the web of paper and prevent buckling 0r slack as it passes over the contact rod, I provide a guide rollerSO beow the rod and a guide roller81 above with a tension roller 82 carried by the arms 83. The tension roller engages the web between the roller 80, and the roll of paper. The arms 83 of this tension roller are held under spring tension by means of the coiled springs 84.

To'facilitate threading the paper in the 'machine the shaft 14 of the upper feed roll 10 is mounted for vertical movement in the bearings 85, see 4. The levers 86 having cams 87 thereon are mounted on the shaft of the lower feed roll so that they may be swung under the shaft of the upper feed roll, thereby liftin it and permitting the ready insertion 0 the paper.

With the parts thus arranged the operation of the machine is as follows: The web of paper having the apertures 8 therein associated in definite relation to the wrapper units is the control means which definitely times the feeding of the paper to the cutting mechanism, and thereby insures cutting at the proper point. The cam 41 is continuously driven with the cutting mechanism. The clutch in the structure illustrated is interposed between the cutting mechanism and the feed rollers.

When the web has been advanced to the proper point the mechanism described, controlled by the contacts acting through the perforations, releases the clutch, thereby stopping the feed at the proper point for cutting, the clutch being immediately reengaged by the cam 41. r

I have illustrated and described my improvements in an embodiment which I have found very practical. I have not attempted to illustrate and describe various modifications and adaptations thereof as I believe this disclosure will enable those skilled in the art to embody or adapt my improvements as may be. desired.

Having thus described my inventlon what I claim as new and desire to secure by Letters Patent is: 4
